Filed: 1982-01-23
Abstract: A stationary ceramic disc (9) and a ceramic disc (10) which can rotate thereon and can be displaced linearly, are arranged in a housing (7) of the mixing valve for hot and cold water. The water temperature can be controlled by the rotation and the water quantity by the linear displacement. A stop ring (24) which can be adjusted in rotation and interacts with stops (21) on the guide bush (16) which is supported such that it can rotate in the housing (7) is provided in the housing (7) in order to limit the mixed water temperature. The operating lever (14) is supported such that it can pivot in the guide bush (16). The operating lever (14) projects through a stop bush (28) which is seated such that it can be adjusted in rotation in the neck part of the guide bush (16). The cone angle of the inner wall of the stop bush (28) reduces continuously in a circumferential section (28a) of approximately 90 DEG . As a result of suitable rotary adjustment of the stop bush (28), the possible pivoting angle of the operating lever (14) is reduced by this inner wall section (28a) on opening the valve, corresponding to the respective gradient of this section. In consequence, the maximum possible outlet flow quantity can be suitably limited. <IMAGE>

Title: System for transmission of binary data signals and associated bit clock signals from a data signal transmitter to a data signal receiver
Inventor: WEDLER HARTMUT DIPL ING
IPC: H04L25/49
Filed: 1982-03-31
Abstract: In a system for transmission of binary data signals and associated bit clock signals in a transmission signal from a data signal transmitter via a transmission path to a data signal receiver, the bit clock signal associated with the respective data signal is extracted at the transmitting end with clock pulses corresponding to the transmission bit rate of the transmission path with the output of a sampling pulse string and, following the occurrence of a 1-0 or 0-1 bit string in the sampling pulse string, is supplemented by a fixed number of bits of the currently present data signal and is output as a transmission signal; at the receiving end, the bits occurring in the fixed number and in sync with the transmission bit rate following the occurrence of a 1-1-0 or 0-0-1 bit string in the transmission signal are evaluated as data bits, while the transmission signal released from the data signal bits serves as a receiver-end bit clock signal of the data signal. <IMAGE>
Patent DE-3215081-A1 (DE)
Inventor: FRUEHAUF WALDEMAR DR
IPC: H02J13/00
Filed: 1982-04-22
Abstract: A house system for the transmission of information messages which are encoded in the form of digital signals wherein a code is selected which facilitates the testing of each information bit, including a central station and a series of substations at which the information messages of the central station are selectively deliverable through the electrical power supply wiring as the transmission path which is utilized by further similar systems. Each substation, due to an erroneously recognized information bit, will terminate the further information evaluation, whereby each of the information messages evidences a selectable subsequence of digital signals which represents a house code which is specific with respect to the applicable house system, which preferably occurs near the beginning of the total sequence of digital signals representing the information message. The central station generates an operating signal when it is transmitting information messages which is received by a monitoring unit. When an information message originating in a neighboring system with the same house code enters into the house system, then the monitoring unit emits a signal, which, due to the lack of the operating signal of its own central station, recognizes this immediately as a foreign (i.e. nonhouse) information message and emits a signal on the transmission path which causes a code alteration in the incomming information message. The substation which is addressed during the sequence receives this information message containing the code alteration, and consequenty terminates further information evaluation.

Title: Low-carat gold alloy
Inventor: OHTSUKA MASASUKE
IPC: A61K6/04
Filed: 1982-06-21
Abstract: A low-carat, corrosion-resistant gold alloy is provided whose outer layer does not become blackened after casting. The alloy is used as a casting alloy for tooth replacement and for jewellery products, or as a contact alloy for use in electrical apparatus. It is composed essentially of gold, palladium and silver, indium being present instead of copper, which is contained in conventional alloys of this type, and zinc or tin components, which are necessary as deoxidising agents, being present. Copper components have hitherto been regarded as desirable in view of the castability and the mechanical strength of the alloy, but this resulted in the surface or outer layer of the alloy being blackened, which made it necessary to wash off the blackened oxide films using a sharp acidic detergent, in particular, for aesthetic considerations. The indium provided instead of copper provides the necessary mechanical properties and, at the same time, an aesthetically attractive silver to grey surface, and makes the washing with sharp acids superfluous.

Title: Method and device for producing radiological tomographic images
Inventor: KINANEN ILMARI DIPL ING
IPC: A61B6/06
Filed: 1982-09-20
Abstract: The radiological method is used for producing both linear and panoramic tomographic images using an apparatus consisting of a stationary stand (1) having a film cassette (4) supported in a moving manner and a radiation source (2) arranged in such a manner that the object to be photographed can be arranged between them and such that the X-ray beam passed through the object is always focused onto the film at the same angle. The radiation source (2) and the film cassette (4) are rotated through the magnitude of a predetermined angle about a common axis (7) while the object is being irradiated. The size of said angle is dependent on the selected presentation method and size, a correspondingly bounded X-ray beam being focused onto the object and the film being exposed during the rotation, to be precise in such a manner that, in the case of linear tomography, the complete region of the object to be presented and the film, which is held stationary during exposure, are exposed simultaneously. In the case of panoramic tomography, only a part of the region to be presented and the correspondingly, continuously transported film are exposed at one time. <IMAGE>
